What is a Pivot Joint?

Pivot joints are part of synovial joints. They are described in two words “Pivot” and “joints”. Therefore, “Pivot” means a point of an object on which another object is moving in an up-and-down position. E.g. In the neck, the Skull moves on the upper point of the neck bone in the position of left, right, or up and down. “Joints” are the places where two bones meet that allow us to move and give flexibility to our body....

Types of Pivot Joints

There is just one axis of rotation possible with a pivot joint. It is also known as the “monaxial joint”. In this joint, the rounded bone fits into a shallow depression in another bone and one bone rotates around another within a concave ring formed in the second bone. A ligament lines this ring to provide smooth motion. There are two major types of Pivot Joints- Radioulnar Joint and Atlas-axis joint. These are explained below:...

Implications of Pivot joints

Forearm rotation: Rotation of the forearm is referred to as pronation and supination. Supination extends the hand’s palm whereas pronation reduces it. In this activities movements are essential like; turning as a screwdriver, turning as a doorknob. Head movement: In this joint movement allows in the position of left, right, or up and down. Although, neck is connected to head. Here, the atlantoaxial joint is a type of pivot joint which is between the first and second cervical vertebrae. Main purpose: Pivot joint function is to allow a body part to rotate around a single point, very similar to the rotation of a wheel because a pivot joint rotates around a single axis, it is often known as a ”rotary joint”.  Muscles work: The muscles that link to the bones that comprise the pivot joints provide rotational movement.Their coordination is must So, that proper muscle control is essential to prevent injury and ensure smooth, controlled rotation around the joint. Damage Tendency: Excessive power, quick blows, and repeated tension can cause damage to pivot joints. These joints are particularly vulnerable to injury from disorders like inflammation, imbalanced muscles, and improper body mechanics....
